    • A massive prestellar clump hosting no high-mass cores 
      Sanhueza, Patricio; Jackson, James; Zhang, Qizhou; Guzmán Fernández, Andrés; Lu, Xing; Stephens, Ian W.; Wang, Ke; Tatematsu, Ken'ichi (IOP Publishing, 2017-06-01)
      The infrared dark cloud (IRDC) G028.23-00.19 hosts a massive (1500M(circle dot)), cold (12 K), and 3.6-70 mu m IR dark clump (MM1) that has the potential to form high-mass stars. We observed this prestellar clump candidate ...
    • ALMA Observations of polarization from dust scattering in the IM lup protoplanetary disk 
      Hull, Charles L. H.; Yang, Haifeng; Li, Zhi-Yun; Kataoka, Akimasa; Stephens, Ian W.; Andrews, Sean; Bai, Xuening; Cleeves, L. Ilsedore; Hughes, A. Meredith; Looney, Leslie; Pérez, L. M.; Wilner, David (IOP Publishing, 2018-06-10)
      We present 870 mu m ALMA observations of polarized dust emission toward the Class II protoplanetary disk IM. Lup. We find that the orientation of the polarized emission is along the minor axis of the disk, and that the ...
    • Linking dense gas from the milky way to external galaxies 
      Stephens, Ian W.; Jackson, James M.; Whitaker, J. Scott; Contreras, Yanett; Guzmán, Andres E.; Sanhueza, Patricio; Foster, Jonathan B.; Rathborne, Jill (IOP Publishing, 2016-06-10)
      In a survey of 65 galaxies, Gao & Solomon found a tight linear relation between the infrared luminosity (L-IR, a proxy for the star formation rate) and the HCN(1-0) luminosity (L-HCN). Wu et al. found that this relation ...
    • The VLA/ALMA nascent disk and multiplicity (VANDAM) survey of Orion protostars. A statistical characterization ... 
      Tobin, John; Sheehan, Patrick; Megeath, S. Thomas; Díaz Rodríguez, Ana; Offner, Stella; Murillo, Nadia; Van 't Hoff, Merel; Van Dishoeck, Ewine; Osorio, Mayra; Anglada, Guillem; Furlan, Elise; Stutz, Amelia; Reynolds, Nickalas; Karnath, Nicole; Fischer, William; Persson, Magnus; Looney, Leslie; Li, Zhi-Yun; Stephens, Ian; Chandler, Claire; Cox, Erin; Dunham, Michael; Tychoniec, Lukasz; Kama, Mihkel; Kratter, Kaitlin; Kounkel, Marina; Mazur, Brian; Maud, Luke; Patel, Lisa; Pérez, Laura; Sadavoy, Sarah; Segura Cox, Dominique; Sharma, Rajeeb; Stephenson, Brian; Watson, Dan; Wyrowski, Friedrich (IOP Publishing, 2020)
      We have conducted a survey of 328 protostars in the Orion molecular clouds with the Atacama Large Millimeter/submillimeter Array at 0.87 mm at a resolution of similar to 0.'' (40au), including observations with the Very ...
